Title: METHOD AND DEVICE FOR THE SPATIALLY RESOLVED MEASUREMENT OF RADIATION SIGNALS
Abstract:
The invention relates to a measuring method and a measuring device for the spatially resolved measurement of radiation signals, in particular light signals, wherein RIfS measurements can be carried out in particular. Two locations are imaged onto a detector (24) in a spatially resolved manner by means of a local modulator (16), and either the intensity difference between the two locations is calculated from the detected signal by modulating the locations using the same Hadamard sequence, wherein one of the Hadamard sequences at one location is inverted compared to the other sequence at the respective other location, and by means of a Hadamard transformation or the intensity difference between the two locations is calculated from the differential signal of the signals of the two locations with the same frequency by means of a Fourier transformation, said signals being amplitude-modulated but phase-shifted relative to one another.
